Save A Baby Kangaroo

Overview

Mathematics can save lives

This case study is an authentic context in which an adult in the Australian Outback attempts to save a young orphaned kangaroo. Through video clips, photographs and data, pupils become familiar with a range of data about the several different species of kangaroo. They use the data to identify which kangaroo has been assigned to them and develop a feeding programme in order to save its life.

Mathematical content

Key stage 3 National Curriculum areas covered include:

Key processes – pupils are expected to identify for themselves the mathematics; put together their own chains of reasoning and use mathematical procedures in combination; create convincing arguments from their evidence; consider their assumptions and the accuracy of their results and communicate effectively; reflect on their approaches and results.

Number and algebra – using rational numbers and their properties and their different representations; rules of arithmetic applied to calculations and manipulation with rational numbers; application of ratio and proportion.

Organisation and pedagogy

There are four teacher-led activities and one pupil-led presentation lesson, each of one hour. It is possible that some of the lessons will take longer than an hour. Each lesson is presented in two formats: as a detailed lesson format for those teachers unfamiliar with extended problem solving tasks and also as a lesson outline for more experienced teachers. A mixture of class, individual and group work is involved. The materials are appropriate for all pupils in Key Stage 3. Each lesson has a small homework task. Access to computers is highly desirable, but not absolutely necessary.
